Image Translation using OpenCV | Python
Translation
cv2.wrapAffine()
Below is the Python code for Image Translation:
import cv2 import numpy as np image = cv2.imread('C:\\gfg\\tomatoes.jpg') # Store height and width of the image height, width = image.shape[:2] quarter_height, quarter_width = height / 4, width / 4 T = np.float32([[1, 0, quarter_width], [0, 1, quarter_height]]) # We use warpAffine to transform # the image using the matrix, T img_translation = cv2.warpAffine(image, T, (width, height)) cv2.imshow("Originalimage", image) cv2.imshow('Translation', img_translation) cv2.waitKey() cv2.destroyAllWindows() |
Output:
Advantages/application of image translation are:
- Hiding a part of the image
- Cropping an image
- Shifting an image
- Animating an image using image translations in loop.
